winter was found to be "loaded."] Quartz mills were nearly all run by steam and the fuel was pine wood cut from the mountain sides, every one taking from these public domains whatever he wanted. The principal features of our mill were twelve large pestles or stamps, weighing 500 pounds each, which were raised up about eighteen inches by machinery and dropped into huge iron mortars onto the small pieces of rock which were constantly fed into them by a man with a shovel. A small stream of water was let into the mortars, and as the rock was crushed into fine sand and powder it went out with the water, through fine screens in front, and passed over long tables, a little inclined, and then over woolen blankets. The tables were covered with large sheets of brightly polished copper. On these polished plates, quicksilver was sprinkled and it was held to the copper by the affinity of the two metals for each other. As the water and powdered rock passed over the tables, the quicksilver, by reason of its chemical attraction for gold, would gather up the fine particles of that metal and, as the two combined, would gradually harden and form an amalgam, somewhat resembling lead. Coarser grains of gold would lodge in the blankets, owing to their weight, while the small particles of rock would pass over with the water. The amalgam was put into a retort and heated over a fire, when the quicksilver would pass off in vapor through a tube into a vessel of water, and then condense, to be again used, while the gold would be left in the retort, to be broken up into small pieces and used as current money. In order to save as much of the gold as possible, these copper plates required close watching, constant care and much rubbing to remove the verdigris that would form. About the first of November our mill was completed, and we expected to operate it a good part of the winter with the quartz of other miners, together with that which we would take out ourselves from our own mines. A large well, or underground cistern, was dug under the mill house, which was fed by copious springs, and promised to furnish an abundant supply of water. To furnish water for the numerous mills about Mountain City and in Nevada gulch a large ditch had been dug, which started up in the mountains near the Snowy range, and wound like a huge serpent around promontories and the sides and heads of numerous gulches, with a slight incline, for some fifteen miles. It passed a
